    Thumbs down

    I'm having a problem with condensation. The combustion chamber keeps filling with water and no the lines are not plugged.And the furnace is level. It will run for about 3 days then fill up and quit working.

    Is there a condensate pump for it or does it drain direct. If pump may want to check operation if you haven't already

    It's a rgra 120 upflow and it's no secret. I disconnect the drain system pressure switch the vent motor will run but won't fire obviously.As soon as i hook it up every thing shuts down

    Hmm Full of.......Water

    Alpo8484.So how is the furnace mounted?Up flow,down flow,horizontal left,horizontal right. Make and model number of the little rascal.I'm going to assume it is a ninty plus percenter.If its not we may have some REAL issues here.And if you will what exactly do you mean bythe combustion chambers are full of water? Any info you can give would be helpful on this end.

    Everything shuts down,you mean the whole thing. The ID blower quits running? The "drain system pressure switch" you speak of,is this connected to the ID blower?

    Do those furnaces have a resevoir of sorts that the ID blower mounts to? If so maybe the hole for the drain never got punched out[factory]. Maybe some PVC filings got washed into it.
